If too much behind-the-scenes info won’t ruin the action for you (in fact, the opposite appears to be the case so far with Stranger Things fans), Matt and Ross Duffer reveal the sentiments that led to some crucial casting decisions in recap number one. For example, Paul Reiser’s role was basically written for him, but Sean Astin as Bob was a fluke—he was originally auditioning for the conspiracy theorist role. Dacre Montgomery’s performance as Billy inspired a whole new look at the character. And that arcade has a very specific ’80s movie antecedent—it has the same name as the arcade in WarGames. If you’ve already reached the end of season two, perhaps these Duffers recaps will give you something to chew on during your inevitable rewatch.
